Struct android_activity::ConfigurationRef

source ·
pub struct ConfigurationRef { /* private fields */ }
Expand description

A (cheaply clonable) reference to this application’s ndk::configuration::Configuration

This provides a thread-safe way to access the latest configuration state for an application without deeply copying the large ndk::configuration::Configuration struct.

If the application is notified of configuration changes then those changes will become visible via pre-existing configuration references.

Implementations§

source§

impl ConfigurationRef

source

pub fn copy(&self) -> Configuration

source

pub fn country(&self) -> Option<String>

Returns the country code, as a String of two characters, if set

Returns the layout direction

source

pub fn mcc(&self) -> i32

Returns the mobile country code.

source

pub fn mnc(&self) -> Option<i32>

impl PartialEq for ConfigurationRef

source§

fn eq(&self, other: &Self) -> bool
